Hi
According to my test, this feature is not currently available.
You can choose to open the file in the browser by default but you cannot choose to open it in a specific workspace.
To get this feature more quickly, you can send a feedback directly to Microsoft to add it in future updates.
To send a feedback in Team you can select the Help button at the bottom lower-left of Teams and then choose Suggest a feature or Give feedback to tell to Microsoft what you think.
Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future.
Thanks for your understanding and support.
